draft 6.x-1.6

This release fixes one bug in the code when creating a new content type the system would try and retrieve the columns and fail because the content type did not exist at that moment.

One new feature too this module is the hook_draft() implemenetation. This hook is designed so that people who are using modules which utilize Ajax to create form elements on the fly once the form is on the screen can populate the form with the pertinent elements if they are trying to load the draft from it. This will allow the draft with the on the fly elements to be loaded correctly in the system.

New Feature:
- #424592 Added hook_draft() to the module this allows other modules that utilize ajax in order
to add more elements too the forms too populate the form array based on the information
stored in the drafts table before the form is displayed. This allows for the module to
work correctly with these module provided someone writes a handler to provide that information

Bug fixes:
- #435532 Fixed bug when the user creates a new content type the system would not check
if the returned fields were indeed valid since on initial creation nothing would
be valid however the system still wanted to utilize it as an array
